TO ALL WHOM IT MAY CONCERN:

Be it known that I, H. W. LIBBEY, of Cleveland, in the county of Cuyahoga, and State of Ohio, have invented certain new and usefulimprovements in Carriage-Top Prop-Rests and I do hereby declare'that the following is a full and complete description of the same, reference being had to the accompanying drawings, making a part of this specification, in which-- I Figure 1 is a perspective view of the rest.

Figure 2 is a longitudinal section.

Like letters of reference refer to like parts in the several views.

This rest consists of'a metallic bush, A, fig. 1, provided with a square hole, B, and which is placed upon the projecting arms by which tlfe braces of the carriage-top are secured. This bush is covered with a piece of rubber tubing, C, and which forms the cushion upon which the braces rest. The propin common use isconstructed of a wooden sleeve or bush, and covered with leather. This bush soon becomes loose in consequence of the shrinking of the wood, and the leather covering, from want of elasticity, soon wears out. But my prop, being provided with a metallic bush or sleeve, will not shrink and get loose; it being covered with a thick coat of elastic rubber, will, by virtue of this elasticity, wear much longer than a covering of leather, as it will yield to the jarring and pressure of the braces, which is very great when driving over rough roads.

I am aware that rubber for the cushion or covering of props has been used, but these cushions have been east especially for the purpose, and were placed on over the projecting arms referred to, without any bush or sleeve, but it has'becn found that when thus placed directly upon the arms, they soon wear through the corners of the hole, the rubber being much thinner at the corners than at the side. They are also quite expensive, 'as the work of casting the cushion with a square hole is attended with much trouble.

In the use of the improved prop this difficulty iso'bviated, as a piece of ordinary rubber pipe is all that is used, which is sprung on over the sleeve, thus making a very inexpensive prop, as the tubing is at all times an article of commerce, and hence can be obtained much cheaper than rubber moulded for the purpose, as before remarked.

It will be seen that rubber-on the corners of the bush is as thick as .the rubber on the sides, which is not the case with the cushions made especially for the prop, hence they will last much longer; and not cut through.

This prop can be'applied to any carriage requiring their use, in place of the old kind, as they can be easily slipped on the arm and fastened in the same manner.

What I claim as my improvement, and desire to secure by Letters Patent, is--- The metallic sleeve A and cushion B, combined as and for the purpose set forth.
